Roll pin tool
Also, if you take a pair of needlenose pliers and grind a notch in the side of the "nose", you can use the pliers to remove and install the pins easily. Basically, you want one part of the pliers to push the pin out into the space created by the notch you just ground out of the the other part of the pliers.
I made a pair about 10 years ago and I use them often. The cheaper the pliers, the easier it is to make the tool.
